Looking for ideas on what foam coring product I could use to make a
dodger hardtop.

A guy in the marina recently cold molded one out of door skins wood
and epoxy. Seems to me that making a male mold and heat draping some
foam or something would be a better approach than driving and removing
3000 staples.

Maybe balsa would drape more easily?

I'll be using 1" Divinycell.

1) Build a male mold using a frame and battens to get the shape, or a door
skin, then cover with plastic sheet..

2) Attach Divinycell with low cost deck screws from the inside. (Weight the
foam down to conform while attaching screws.)

3) Glass the outside.

Remove screws, lift from mold, then glass the inside.

Fair out as necessary.

There's a bit of a learning curve in heat forming foam. Not enough heat and
it breaks. Too much and it's not exactly foam. Also, there's a capital
investment in whatever heating apparatus you choose.
For a small project, consider strip planking with foam.

Maybe a scored foam depending on how much curve you need.

Try your local plastic store in the yellow pages or
www.aircraftspruce.com

Start with the manufacturer, Diab Group at http://www.diabgroup.com/
If you want less than a truckload, they'll refer you to their distributor
near you.

Here is the best source I have found for less than case quantities:
http://www.fiberglasssupply.com/Prod...materials.html

For full cases try Composites One or one of the other big distributors
that service professional builders.

I'm building a 45' cutter in strip/composite. Watch my progress (or lack
there of) at: http://www.rutuonline.com

BTW, Divinicell is a thermoset plastic and not very heat shapeable. It
puts off great quantities of formaldehide fumes when it gets hot enough
to melt.
